The rapid growth of wind power in the United States has resulted in two new factories to manufacture wind turbine blades. Knight & Carver opened its wind blade manufacturing and repair facility in Howard, South Dakota, on March 6th. The new facility will serve as the wind blade headquarters for Knight & Carver, which was previously better known for building yachts. The 26,000-square-foot facility will employ as many as 25 full-time employees in 2007, with plans to expand to a 25-person workforce within two years.Meanwhile, Vestas announced on March 20th that it has decided to build a wind blade factory in Windsor, Colorado. The new $60 million facility, located between Fort Collins and Greeley, will have a production capacity of 1,200 blades per year and will employ about 400 people. The Danish company bills itself as the leading supplier of wind power technology in the world, and has already installed more than 9,300 wind turbines in the United States. In early March, Vestas received an order for eight of its 3-megawatt wind turbines, which will be installed at the Tehachapi Pass in Southern California as part of an effort to install 1,500 megawatts of wind power there. Construction on the new blade factory will begin soon, and the factory will start producing wind turbine blades in early 2008.
